  • Setup connectors in Exchange 2010 for 2 servers

    Hi experts,

    Need your help here.

    We have 2 new exchange server (name M1 and M2) and currently trying to setup a connectors
    All the mailboxes are in M2.

    Now; we want all the emails are flowing to M1 then goes to outside world (internet). Same thing as from the external email; the external email going to M1 first then go to M2

    We also want to setup a connector from M2 that goes straight to the Internet (lower cost) if M1 is down or the link on M1 is down

    I just bit confuse whether I have to create an Internal, Internet, Partner or custom connector in Exchange 2010

    Please advise.

      I am not sure what is confusing about the type of connector to create.
      If you are sending email to the Internet, then you create a connector of type Internet. The fact that you want to send the email via another server (which must hold the hub transport role) doesn't make any difference.

        Hi Ossian,
        both servers have Mailbox; CAS; Hub and UM role

        Hi Sembee,
        I'm pretty new with Exchange 2010; so I just want to confirm with the experts like you.

        I'm pretty sure that I need to have Internet connector on my M1 box; because M1 send an email to outside world.

        I'm not sure what connectors should I have on M2 box; as M2 needs to flow all the emails to M1 then goes to outside world. However; M2 also needs to be able to send emails if M1 is down.

        I'm also not sure about the receive connectors; should I just use the default "receive connectors" by allowing "anonymous users", "exchange users", "Exchange servers" and "Legacy"?

        Please advise.

        Thank you very much in advance

          Send Connectors do not belong to a server - they are an org setting.
          Therefore you would just create two connectors, with different servers listed on them. However I am pretty sure that you cannot set the connectors in the way that you want them to. The connectors will usually use the lowest cost and if they cannot reach the server will simply queue the email.

          The Receive Connectors should not be touched, other than enabling anonymous on any server that is accepting email from the Internet.

            Hi Sembee,

            If I set the connectors:

            Internet1 - Cost 1 point to smtp.domain.com
            Internet2 - Cost 5 point to smtp2.domain.com
            We have 2 different internet link for the above setup

            I'm assuming with the above setup; the email will go to Internet1 to send out an email; and if Internet1 is down; then it will use Internet2 connector to send out an email.

            Do you think the above setup will work?

            As for the receive; do you think I can disable "exchange users", "Exchange servers" and "Legacy"??

            Sorry Sembee, I just really want to make sure that I've done everything correctly from my end here.

            Thanks very much for your help.

            Cheers.

              Why do you want to disable those options on the Receive Connector? In the main the receive connector should not be touched at all. Remember it isn't just traffic that comes in from the Internet that uses Receive Connectors, but also inter-server traffic. The simple rule with Exchange is don't touch unless you have to.

              However, with regards to your Send Connectors, I don't think you are going to be able to achieve what you want to. As far as I am aware, local server precedence takes effect, so mail originating on the local server will be routed by that server, rather than being sent to an external server.
              The only way that you could force the traffic through the other server is by having no Send Connector at all on the first server.

              Simon.

                Hi Sembee,

                just 1 more question; then i will setup a time to try the connectors.

                On my Send connectors
                on the column "Specify the FQDN this connector will provide in response to HELO or EHLO:"


                on my M1 box
                M1.domain.com.au

                on my M2 box
                M2.domain.com.au

                is this correct? or I should just left that box empty?

                please advise

                  The FQDN should match the PTR on the external IP address for the server.
